    • Impressions from the Internet Architecture Board E-Impact Workshop

      The IAB ran an online workshop in December 2022 to begin to explore and understand the environmental impacts of the Internet. The discussion was active, and it will take time to summarise and produce the workshop report – but the topic is important, so we wanted to share some early impressions of the outcomes.

    Assessment criteria for decision on in-person/virtual IETF 108

    • Jay DaleyIETF Executive Director
    • Alissa CooperIETF Chair
    • Colin PerkinsIRTF Chair

    17 Apr 2020

    As set out in our recent email and blog post, we have developed an assessment framework and decision making process for the decision on whether or not the in-person IETF 108 Madrid can go ahead. The proposed framework and process is detailed below and we welcome community feedback.

    Given the current conditions in Spain and around the world, the framework is based on the assumption that these conditions would have to significantly improve for the in-person meeting to be held.  The assessment will consider some of the venue selection criteria specified in RFC 8718, adapted to the situation we are in.

    Assessment Framework

    As a matter of principle, we want an assessment framework that, as much as possible, uses independent, trusted data to enable an objective assessment.  However, as this is an entirely novel situation, high quality data sources are not yet available and so there will be, by necessity, a significant degree of subjective judgement in our assessment.

    The assessment criteria we have chosen are based on the venue selection criteria specified in RFC 8718, both the mandatory criteria of section 3.1 and the important criteria of section 3.2.1 “Venue City Criteria”, which we believe make up the most relevant and recent advice from the community that can be applied in these circumstances.  If any of the mandatory venue selection criteria from section 3.1 of RFC 8178 cannot be met then the in-person meeting will not go ahead. Those criteria relate to the physical facility (space, access, network).

    The important venue selection criteria from section 3.2.1 of RFC 8718, listed below in a different order from the RFC, are more complex to assess as explained below:

    “Economic, safety, and health risks associated with this Venue are acceptable.”

    When considering our data sources we want to use both local sources and independent sources to ensure any possible bias is minimised. Our primary local sources will be the official Madrid Tourism COVID-19 site and our local contacts and if either indicates that any form of local emergency conditions still prevail then the in-person meeting will not go ahead.

    The selection of independent sources is more problematic and we have chosen to use the US CDC and their travel advisory for Spain, which must be below Warning Level 3 (avoid nonessential travel) or the in-person meeting will not go ahead.  While recognising that the choice of a single US source may be contentious, we believe this is the best choice because all of our contracts have a force majeure clause that specifically lists the US CDC.

    “Travel barriers to entry, including visa requirements, are likely to be such that an overwhelming majority of participants who wish to do so can attend.  The term "travel barriers" is to be read broadly by the IASA in the context of whether a successful meeting can be had.”

    Assessment of this criteria has two parts to it.  The first is a definition of what are unacceptable travel barriers and the second is deciding how to apply the “overwhelming majority” test.  Unacceptable travel barriers come in two forms, those that would preclude an in-person meeting entirely and those that will be counted on a per-country basis for an “overwhelming majority” test (as explained below):

    Unacceptable travel barriers that would preclude an in-person meeting are:

    • Spanish borders closed to visitors
    • Any form of quarantine on arrival in Spain
    • Any form of self-isolation requirement on arrival of more than 24 hours
    • Any new form of health-related travel restriction imposed by Spain or the EU that is inherently discriminatory in nature (e.g. not based on science).

    Unacceptable travel barriers that will be counted on a per-country basis are:

    • Any form of quarantine on return.
    • Any form of self-isolation requirement on return of more than 24 hours unless consistent with general self-isolation requirements
    • Government travel bans

    A requirement to prove COVID-19 immunity, vaccination or similar will be acceptable provided it is not inherently discriminatory, though calculating the impact of that is likely to be problematic.

    In order to assess this criteria, in particular the “overwhelming majority” requirement, and the criteria below, we will use a similar methodology.  Using our records of attendance at recent European IETF meetings we will develop an expected distribution of participants by country (i.e. how many participants we would typically expect from each country).  If we judge that more than 20% of expected participants cannot attend, based on this country distribution, then the in-person meeting will not go ahead.

    Using the definitions above of unacceptable travel barriers, we will sum the percentages derived above from each country that is judged as having unacceptable barriers and if that figure is greater than 20% then the in-person meeting will not go ahead.

    “Travel to the Venue is acceptable based on cost, time, and burden for participants traveling from multiple regions.  It is anticipated that the burden borne will generally be shared over the course of multiple years.”

    Using the same basic methodology as the criteria above, for this criteria we will aim to assess flight availability for each country to get to Madrid and if less than 50% of normal flights/routes between the two countries are available or the fares are significantly above normal then we will work on the assumption that the burden of travel for people from that country is not acceptable.

    We will then sum the expected percentages of participants from each country that is judged as having unacceptable travel burdens and if that figure is greater than 20% then the in-person meeting will not go ahead.

    Finally, we note that there is the possibility that the result of this assessment is that an in-person meeting can go ahead but corporate travel bans remain in place and/or many people are unwilling to travel, in which case we will engage in a subsequent process after May 15 to establish the viability of an in-person meeting, as we did for IETF 107.


    This process has been designed to respect the various delegated roles with the IETF leadership and ensure there are appropriate checks and balances in place.

    1. On or about 11 May 2020 the IETF Executive Director will produce a draft report using the assessment framework set out above with a recommendation on whether or not an in-person meeting can be held.  This draft report will be confidential and distribution restricted to the IESG, IRTF Chair, IAB Chair, LLC, Secretariat and meeting host primary contact.  
    2. On 12 May 2020 the IESG, IRTF Chair, IAB Chair, LLC and Secretariat will meet to discuss the draft report and any changes that need to be made. The objective will be to get consensus on the report’s recommendation among the IESG, the IRTF Chair, the IAB Chair, the LLC Board, and the IETF Executive Director.
    3. By 14 May the IETF Executive Director will produce a final report.  At this stage the final report will be confidential and distribution restricted to the IESG, IRTF Chair, IAB Chair, LLC, Secretariat and meeting host primary contact.
    4. On 14 May 2020 the LLC Board will meet and officially sign off the recommendation.  The LLC will then officially inform the IESG of its recommendation.
    5. On 15 May 2020 the decision will be announced and the final report made public.

    We now welcome your feedback about the assessment framework. Please send your feedback to (which will reach the IESG, IRTF Chair, and IETF Executive Director) by April 27. As you will have seen, this is a very complex situation requiring complex analysis and so please make any feedback as practical and implementable as possible within the published time frame.
